3D model of the selected object
 Raclavský, David ; Hanzl, Vlastimil (referee) ; Kalvoda, Petr (advisor)
The result of the diploma thesis is a photogrammetrically evaluated georeferenced 3D model of an object with its environment, located in the AdMaS complex. The work describes in detail all phases of creating a 3D model of the object from the selection and calibration of the camera to editing the 3D model. Discuss about software and methods for evaluating 3D models. The thesis deals with the optimal setting of ContectCapture software. The accuracy of the resulting 3D model is tested by the methodology according to ČSN 013410 on the basis of control measurements.

Editing 3D Models Using Physical Simulation
 Dzurenko, Martin ; Kmoch, Petr (advisor) ; Yaghob, Jakub (referee)
Simulation of 3D models is an important part of computer graphics. Real-time rendering of material deformations is widely used in animations. Regarding the animations, the deformations of materials must be plausible for public audience, not necessarily physically accurate. Mass-spring systems method offers a solution that decomposes objects to hexahedral elements. The element mesh define a spring system governed by Newton dynamics. Parameters used to set up material characteristics on the springs are Poisson's ratio, Young's modulus of elasticity and density of the material. The mesh dynamics are solved using integration methods which apply ordinary differential equations. The thesis presents application of the solution in a simple windowed editor for users unfamiliar with the topic. Core algorithms and implementation are discussed in detail. The editor supports internal save files, exporting of deformed objects and multiple integration methods. Comparison of the used methods is presented in terms of speed, accuracy and stability.
